多点起爆网络结构参数设计及其同步性误差分析

设计了一种8点环形同步起爆网络,网络结构采用典型的板式结构,传爆炸药为新型纳米颗粒炸药(黑索今(RDX)/奥克托今(HMX)=45%/45%,10%的含能粘结剂,炸药颗粒直径小于100 nm),试验和仿真确定了起爆网络的关键结构参数为:刻槽宽度为1.2 mm,基板厚度为3.8 mm。理论分析起爆网络的同步性,发现所设计的同步起爆网络八个输出端的同步性误差最大值不超过152.2 ns,实验验证表明,所设计的起爆网络同步起爆精度约为170 ns,满足聚能装药多模式战斗部形成外形良好的侵彻体的要求,实弹检验表明,刚性8点同步起爆网络可以形成成型良好,横向偏移较小的射流战斗部,满足聚能战斗部的使用要求。

Design and Synchronization Analysis of Structural Parameter of a Multi-point Explosive Circuit

A synchronous explosive circuit with the typical plate structure was put forward with the booster explosive containing 45% RDX,45% HMX and 10% energetic binder. The diameter of explosive particles were smaller than 100 nm. The key structural parameters of this explosive circuit are obtained by test and simulation as notch width 1.2 mm,and parent plate thickness 3.8 mm. The synchronization of the explosive circuit was theoretical analyzed. Results show that the maximum value of the synchronization error of eight output parts are less than 152.2 ns. The experimental verification show that the initiating bursting precision of the explosive circuit is about 170 ns,which meets the requirement of multi-mode warhead forming a good shape penetrator. The live projectile test show that the eight-point synchronous explosive circuit can form a jet warhead with a good shaping and relatively smaller lateral offset,which meets the operational requirement of the shaped charge warhead.
